It looks like erlang doesn't know where to find the .beam files for the
ppool application. You can tell Erlang to search additional directories
for .beam files with the -pa command line option.

Try this:

$ cd learn-you-some-erlang/ppool-1.0
$ erlang -pa ebin/

Then do


in the Erlang shell.

If that gives the same error, do


then try application:start(ppool). again.
